ANN ARBOR, Mich. -- Michigan had another week and another offensive shift against Iowa, this time bringing back an offense the Wolverines tested briefly last season but employed to a much larger capability Saturday in a 42-17 win over the Hawkeyes.

It showed the true devastation having Devin Gardner and Denard Robinson on the field at the same time could do, and Michigan hasn’t even unleashed all of it yet, as Robinson did not attempt a pass on Saturday.

His new role, which could approximate his NFL future, sent him darting back up the Michigan 10, the Wolverines’ weekly power rankings.

Devin Gardner accounted for six touchdowns against Iowa.

1. QB Devin Gardner (1): The junior made his third career start and did something no Michigan quarterback had done since 1983 -- account for six touchdowns in a single game. Gardner completed 18-of-23 passes for 314 yards and three touchdowns and also rushed for three touchdowns. Each week he looks more and more comfortable at the helm.

2. QB/RB/WR Denard Robinson (8): The senior returned and played all over the field. While he didn’t attempt a pass, Robinson ran out of the quarterback spot, out of a typical running back position and caught passes as a slot wide receiver. He accounted for 122 yards of total offense in his final home game.

3. LB Jake Ryan (2): Another week, another good performance for Ryan, who had six tackles, a tackle for loss and forced a fumble. He leads Michigan with 75 tackles and 13 tackles for loss. His 3.5 sacks are second on the team. He leads Michigan in forced fumbles (three) and quarterback hurries (two) and is tied for second in pass breakups, with three.

4. LB Kenny Demens (3): The fifth-year senior had five tackles and a tackle for loss against Iowa on Saturday, once again manning the middle of the Michigan defense. He is now second on Michigan in tackles, with 72, and third on the Wolverines in tackles for loss, with six, although he has no sacks.

5. WR Roy Roundtree (4): The late-career rejuvenation of Roundtree continued on Saturday with a five-catch, 83-yard performance. In the past three games, he has caught 12 passes for 286 yards and a touchdown. In his first eight games this season, Roundtree had 13 catches for 175 yards and a score.

6. WR Jeremy Gallon (7): As Roundtree has improved, so has Gallon. The junior had five catches for 133 yards against Iowa, the third consecutive game in which he has had more than 70 yards receiving. Gallon is Michigan’s leader in receptions (34) and yards (617) and also has two touchdowns.

7. S Jordan Kovacs (5): Michigan’s defensive captain had five tackles and a sack during his final home game. He has 59 tackles this season and 325 in his career, one behind Andy Moeller for 12th on the career tackles list at Michigan.

8. RB Thomas Rawls: (NR): Rawls might not be very productive, but with Fitzgerald Toussaint’s injury, Michigan will likely look to senior Vincent Smith and the sophomore Rawls, who had 22 yards on eight carries against Iowa and has 240 yards and four touchdowns this season. Depending on Michigan’s formation, more carries could come to Rawls shortly.

9. S Thomas Gordon (6): Another week, another five tackles for Gordon, who consistently brings those sorts of numbers to Michigan. He added a pass breakup Saturday, but he has had five or more tackles in the past five games and in nine of 11 games this season.

10. K Brendan Gibbons (NR): Frankly, Gibbons was probably an omission from last week’s power rankings after making the game-tying field goal against Northwestern. He didn’t have much to do against Iowa, but Gibbons has been remarkably consistent this season, making 14 of 16 field goals with a long of 52 yards. He has made 11 in a row, dating to missing a 44-yarder against Purdue.
